JBoss = WildFly, OK?

WildFly 8 versus TomEE versus WebLogic, and other matters

Jason Greene, WildFly 8 Architect, weighs in on confusing name changes, transition issues, and why you should be excited about this app server.

“Jboss = WildFly? Why the different name?”
asked one Redditor, responding to linked press release about the
launch of WildFly 8. Ironically, the point of the rebranding is
part of an effort on the side of RedHat to reduce this confusion.
We at JAXenter have noticed a few similar responses to our own
WildFly news, so we thought we’d grab Jason Greene, WildFly 8
Architect, and find out how the community at large is adjusting.
While we were at it, also wanted to find out how the team thinks
their software stands up against its biggest rivals, and what the
biggest changes are in the latest incarnation of the community app
server.

JAX: Now that GlassFish is lacking commercial
support, there are several contenders for companies looking for an
alternative – how would you say they compare to WildFly
8.0?

Greene: WildFly and TomEE are both
open-source, light-weight and developer friendly. WebLogic, on the
other hand, is proprietary and heavy-weight. It’s our belief that
open-source is essential for an application server because it is so
tightly coupled with your application.

The big difference between TomEE and WildFly is that
WildFly offers a great deal more features

If you are debugging your application it is invaluable
to be able to look under the hood, and see what is happening.
Developer friendliness is also important because it has a direct
impact on a development team’s productivity.

The big difference between TomEE and WildFly is that
WildFly offers a great deal more features. WildFly includes the
full Java EE platform, whereas TomEE just provides the Web Profile.
WildFly offers advanced administrative and operations capabilities,
whereas TomEE is just focused on providing an application runtime.
That said, not providing these additional capabilities means that
TomEE is able to offer a very slim disk footprint.

What do you think are the key features of this
release?

The biggest feature everyone has been waiting for is
Java EE7 support. Although it’s not just about features, I think
everyone is excited to see our first community final release after
the big WildFly/JBoss EAP split. This release is somewhat special
in that the community was involved in every step along the way,
including naming the project.

On the subject of the big name switch – do you
think people are still confused about the change?

I think now that we have gone through a full release
cycle, and put up a lot of resources about the project, that the
impacts of the project and product split are quite a bit clearer.
That said, everyone won’t be completely adjusted until they have
been using the new project for a while.

What are the most significant
changes?

This is a large release with a number of changes. The
most significant feature is that WildFly 8 is Java EE7 certified,
meeting both the full and Web Profiles. Java EE7 improves developer
productivity and provides a rich set of APIs and capabilities that
make meeting the technical demands applications face easier than
ever.

Another important change is that WildFly 8 includes a
new lightweight, highly performant and scalable web server called
Undertow. Undertow supports both non-blocking and blocking styles
of web development, as well as the latest standards such as Web
Sockets. It is also a highly customizable and flexible server with
the ability to handle everything from dynamic routing to custom
protocols. In addition, it can function as an efficient reverse
proxy or file server, removing the need to use a traditional native
web server in your environment.

 The most significant feature is that WildFly 8
is Java EE7 certified, meeting both the full and Web Profiles

Also noteworthy is that WildFly 8 includes a number of
operational improvements. The management API and administration
console now support role-based access control (RBAC), as well as
auditing via a new audit log facility. These capabilities enable an
organization to segment administrative and operational
responsibilities across different users and teams.

Finally, WildFly 8 has added the infrastructure to
support patching. Future releases will provide an additional patch
option for our users to download.

Is there anything you think people will struggle
with in updating to or transitioning from other servers to WildFly
8.0, and if so, are there any resources you can recommend to help
them?

Every application server does things a little bit
differently, so migrating to WildFly from another vender will
require some porting effort. That said, we have already taken steps
to make migration easier, and we will continue to do so. As an
example, we support a number of different JPA providers. which
usually allows someone migrating to reuse the same JPA
implementation they were using before.

As to specific resources, two members of our community
recently published a useful mini-guide on migrating from Glassfish
to WildFly 8 on our blog. Over time I suspect we will build up lots
of wikis and guides covering the various types of conversions. In
the meantime our forums are a great way to reach out to others, and
our community is always very helpful. A number of them have been
through migrations and/or are experts in other server platforms as
well.

What was the most difficult part about putting
8.0 together? Were there any major challenges?

The biggest challenge was the amount of work we had
going on all at the same time. Getting certified on a new major
release of the Java EE platform is a big enough challenge on its
own, but on top of that we delivered significant management
functionality and a new web server. At the same time we also went
through a major project rename, and delivered a number of
significant JBoss EAP releases as well. It all came together though
thanks to the hard work of the talented WildFly contributors.

Have you noticed a significant increase in
uptake of WildFly since last November*? (*when Oracle made its

announcement
about the future of GlassFish)

Yes definitely. We have always been blessed with
enthusiastic users, so we have had a lot of interest in all the of
8’s milestone releases. However, a lot of users like to wait until
a late Beta or a CR before they try it out. We certainly saw a big
increase in interest after we launched CR1, and even more when we
announced certification and the final release.
